WARNING

Installation

3A7469D 7

Installation

Grounding

Check your local electrical code and pump

or sprayer manual for detailed grounding

instructions.

Spray gun: ground through connection to a

properly grounded fluid hose and pump.

Fluid hose: use only electrically conductive

hoses with a maximum of 500 ft. (150 m)

combined hose length to ensure grounding

continuity. Check electrical resistance of

hoses. If total resistance to ground exceeds

29 megohms, replace hose immediately.

Fluid supply container: follow local code.

Object being sprayed: follow local code.

Solvent pails used when flushing: follow

local code. Use only conductive metal pails,

placed on a grounded surface. Do not place

the pail on a nonconductive surface, such as

paper or cardboard, which interrupts

grounding continuity.

To maintain grounding continuity when

flushing or relieving pressure: hold metal

part of the spray gun firmly to the side of a

grounded metal pail, then trigger the gun.

System Requirements

•Install a bleed-type master air valve on a

pneumatic pump air supply line to relieve

air trapped between this valve and pump

after air regulator is shut off. Trapped air

can cause the pump to cycle

unexpectedly.

•Install a fluid drain valve between the

pump and gun to relieve pressure in

displacement pump, hose, and gun.

Triggering to relieve pressure may not

be sufficient. See the Pressure Relief

Procedure, page 9.

Gun Trigger Lock

The equipment must be grounded to

reduce the risk of static sparking. Static

sparking can cause fumes to ignite or

explode. Grounding provides an escape

wire for the electric current.

To prevent injury when the gun is not in

use, always engage the gun’s trigger lock

if unit is being shut down or left

unattended. A wallet-sized warning card

with important injection treatment

information is included with the gun.

Additional cards are available at no

charge. Provide a card to all operators.

The trigger lock must move freely, and

easily snap into the locked position. If the

trigger lock is damaged or movement is

restricted, replace with new trigger kit (16)

immediately.
